The objective of this study was to examine the effect of different concentrations of trehalose and
raffinose in Tris-citric acid-glucose (TCG) egg yolk extender for the sperm freezability of Red Maasai
sheep, another African breed- the Dorper and their crosses. The results showed that Red Maasai,
Dorper and their crosses sperm could be cryopreserved by extending with 0.075 to 0.01 M trehalose or
raffinose-TCG egg yolk extender. We conclude that the cryopreservation of currently under threat Red
Maasai sheep due to uncontrolled exotic breeds sperm makes it possible to establish a gene bank for
the storage of animal genetic resources for endangered species, under the management of the
International Livestock Research Institute for future genetic options in an uncertain world
